The utility model is provided with at least two primary thimbles and back-off thimbles which are vertically arranged at the lower end of the die cavity, when in demoulding, the ejector pin firstly goes in and out for demoulding, and then the primary thimbles and the back-off thimbles are ejected for demoulding together, so that the demoulding effect is good and the efficiency is high; the event the utility model has the advantages of novel in design, simple structure, demoulding effect is good, and is efficient.
Description
Technical Field
The utility model relates to an injection mold technical field especially relates to a secondary ejection demoulding mechanism.
Background
The die is various dies and tools for obtaining required products by injection molding, blow molding, extrusion, die casting or forging forming, smelting, stamping and other methods in industrial production. The mould is provided with a mould cavity which is consistent with the shape of the product and is used for forming the product. Some products produced by the die have complex workpiece structures, more holes with grooves are formed, inverted buckle structures possibly exist in die cavities of the die, ejection in the product demolding process needs to be performed in unconventional ejection modes such as inclined ejection, overturning and the like for demolding, the unconventional ejection demolding modes usually need complex control modes for matching, the control cost is increased, and the production efficiency is reduced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a secondary ejection demoulding mechanism to prior art not enough, this secondary ejection demoulding mechanism modern design, simple structure, demoulding effect is good, and is efficient.
In order to achieve the above purpose, the present invention is achieved by the following technical solutions.
The utility model provides a secondary ejection demoulding mechanism, including cope match-plate pattern and lower bolster, the upper die benevolence has been installed to the cope match-plate pattern lower extreme, the lower bolster upper end is installed and is corresponded the lower mould benevolence that matches with the upper mould benevolence, and be provided with the die cavity between lower mould benevolence and the upper mould benevolence, at least two thimbles and back-off thimble that are vertical arrangement have been installed to the die cavity lower extreme, and install in a thimble board upper end under the thimble of once, install in back-off thimble board upper end under the back-off thimble, and back-off thimble board installs in a thimble board upper end.
Wherein, the upper end of the upper template is provided with a panel.
The lower end of the lower template is provided with a bottom plate through square iron.
The primary ejector pin plate and the reverse ejector pin plate are arranged at the lower end of the lower template.
The utility model has the advantages that: a secondary ejection demoulding mechanism, including cope match-plate pattern and lower bolster, the upper die benevolence has been installed to the cope match-plate pattern lower extreme, the lower mould benevolence that corresponds the matching with last mould benevolence has been installed to the lower bolster upper end, and is provided with the die cavity between lower mould benevolence and the last mould benevolence, the die cavity lower extreme is installed two at least thimbles and back-off thimble that are vertical arrangement, and install in thimble board upper end under the thimble, install in back-off thimble board upper end under the back-off thimble, and back-off thimble board installs in thimble board upper end. The utility model is provided with at least two primary thimbles and back-off thimbles which are vertically arranged at the lower end of the die cavity, when in demoulding, the ejector pin firstly goes in and out for demoulding, and then the primary thimbles and the back-off thimbles are ejected for demoulding together, so that the demoulding effect is good and the efficiency is high; the event the utility model has the advantages of novel in design, simple structure, demoulding effect is good, and is efficient.
